I had considered a similar arrangement to Lonnies for cabin heat taking
the exit air from my rear placed oil cooler.  However, I read about a
lycoming powered RV aircraft where the builder had done a similar thing
with his lycoming oil cooler.  His experienced indicated that on cold
days the oil temp apparently dropped to the point he was not getting
much heat from the arrangement.  On the other hand if your oil temp
stays steady >180F then I would think it should work.
In my case I have a similar problem as the lycoming guy.  Since I don't
have a thermostat (nor cowl flaps - Paul {:>}) my coolant temp on cold
days can drop below 140F which does not provide any significant cabin
heat.  I intend to either add cowl flaps and close off some of the air
intake or stick in a thermostat (thermostat is easier).

Stick in the cowl flaps. In just a few more months you will want more
speed. Speed in an airplane is like money. You can never have enough.
